You can compare and add a policy to the Manager from a different location on your network or from a storage device.
Note
Visibility rules, as they pertain to a policy being available to a child domain, apply to imported policies. Thus, for any custom (created or cloned) policy you import, if you unchecked the Visible to Child Admin Domains checkbox during creation, the imported policy will only be visible in the Admin Domain.
Importing and comparing policies involves the following:
Selecting a policy to import
Comparing policies before importing
Completing the policy import
